10 Claims.

A further object of this invention is to provide J a stereotype mat-casting device which comprises, with a body or stick formed to cooperatively engage with the table opening of a type-casting machine, a lock-up slide disposed in longitudinally slidable relation in a matrix receiving channel in the body, the channel being approximately the same length as said slide and open only at one end, the slide seating against a matrix in said channel and having a casting opening or slot therein registering with said matrix, and a normally fixed but releasable cross slide engaging in holding relation across one end of the lock-up slide at the open end of the channel; said lockup slide projecting beyond the corresponding face of the body and arranged for inward movement upon engagement by the movable mold of the machine so'as to urge said slide into positive lock-up relation with the matrix.

A further object of the invention is to produce a simple and inexpensive device, and yet one which will be exceedingly effective for the purpose for which it is designed.

These objects We accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawing similar characters of reference indicate corresponding parts in the several views:

Figure 1 is a plan view of our improved stereotype casting device.

Figure 2 is a longitudinal section illustrating the lock-up slide and cross slide in operative position,

Figure 3 is a similar view, but showing the cross slide retracted from the path of the lock-up slide, and the latter partially withdrawn from the body.

Figure 4 is a front end view of the device disposed in upwardly facing position.

Figure 5 is a cross section on line 55 of Fig. 2.

Figure 6 is a front end view of the device in the inverted position which it occupies when mounted on the type casting machine.

Referring now more particularly to the characters of reference on the drawing, the device comprises an elongated body or stick I, which is notched inwardly from the face 2 along the outer longitudinal edges thereof as at 3.

Between the notches 3 the body I is formed with a relatively shallow channel 4 which is open at one end to the front end of the body; the other end of said channel being closed by an end wall 5. The channel 4 is of a Width and length to receive, in seated relation in the bottom thereof, a fiat stereotype matrix 6 which carries the impression"! in the outer face thereof; said matrix being pre-formed, as usual, from a relatively heavy strip of mat paper.

A lock-up slide 8 slidably engages in the channel 4 from the initially open end thereof, said slide being the same length as the channel, and being formed with a longitudinally extending slot 9 of a size and configuration to expose the working portion of the face of the stereotype matrix 6. In other words, the slide 8 engages only about the marginal portion of the matrix- 6.

A5 clearly shown in Fig. 5, the slide 8 is provided, as at III, with a dovetail fit in the channel 4.

The height of the slide 8 is such that when the inner face of the slide is disposed in engagement with the matrix 6, the outer face H of said slide is disposed in a horizontal plane outwardly of the horizontal plane of 'face 2 of the body I. In addition to such outward projection of the slide, as above, said slide is capable of limited inward movement by virtue of the dovetail mounting thereof. These structural features are important, for the reason as will hereinafter appear.

When the slide 8 is fully engaged in the channel 4 it is normally held against accidental escape by means of a cross slide l2 dovetailed, as at l3, into the front end of the body I for sliding movement from a position overlapping the initially open end of said channel, as shown in Fig. 2, to a position clear of the channel 4, as shown in Fig. 3. The cross slide I2 is formed with a vertically elongated slot S through which a retaining screw l4 pro- J'ects; the inner end of said screw being threaded into the body, while the outer end of said screw is provided with a thumb engaging head 15.

In use of the above described stereotype casting device, the same is disposed in an inverted position, as'shown in Fig. 6, and engaged in cooperative relation with the opening it in the table l! of a conventional type casting machine (not shown), such as the Ludlow; the device being held against lateral displacement by engagement of the notches 3 with corresponding portions of the table H on opposite sides of opening l6. As so positioned the device is engaged from above and thus held against vertical displacement by means of a lock-down lever unit (not shown) but which is also conventional on. type. casting ma.- chines.

As so mounted the casting device is ready for use, Thereafter the mold, together with included.

mouthpiece of the type casting machine, as indicated diagrammatically at I8, is raised untill the upper face of said mold forcefully engages with. the outer face of the lock-up slide 8. As the face:

H of said lock-up slide projects outwardly beyond the face 2 of the body, and as: said slide is capable of limited inward movement, the force.- ful engagement of the mold IS with said slide pushes the latter tightly against. thematrix' for thecasting. operation. This provides a lock-up on the matrix so tight that there is no-possibility of; molten metal: flowingpast the matrix. This is. a valuable safety feature, which is also enhanced by the dovetail mounting of the: cross slide; 132 which prevents any possible" escape of the molten metal in the direction of the-operator.

With the several parts engaged as. above, molten metal is introduced from the mold l'8 through. the opening a and against the matrix 6, to form thedesired stereotype: mat. After the molten metal: has been introduced. and has been permitted to; harden, thebiodyl is. removed from the type: castin machine, and thestereotype mat is' withdrawn from-the slide; 8.; the inner walls l-9 of-sa-id' slide slightly diverging outwardly to facilir tate removal of the formed: mat.

In. order to. remove and. replace the matrix 6 it is onlynecessary to unloosen. the screw 14, shift the: cross. slide: 1-2. clear ofv channel- 4, and to then: withdraw the slide 8 and the matrix 6- from said' channeh From the: foregoing description it will bereadily seem that, we have produced such. a. device as substantially fulfills the objects.- of the invention as set forth herein.

While this specification, sets forth in detail the present and preferred construction of the device, still! in practice such deviations from. such' detail may be resortedto as do not form a departure from the spirit of the invention, as defined by the appended: claimsa.
